Title: Improved process for viscose production
IPC: C08B9/00
Filed: 1958-01-02
Abstract: A controlled depolymerization of cellulose is effected by subjecting cellulose to ionizing radiation of an intensity between 0.05 and 60 watt-second/gram of cellulose.  The ionizing radiation may be of the particle or the electromagnetic kind.  In the manufacture of viscose in which cellulose is alkalized and treated with carbon disulphide, the xanthate thus formed being dissolved in sodium hydroxide solution and filtered to yield viscose, the ionizing radiation may be applied at any stage in the process. Alternatively a short period of irradiation of the alkali cellulose may be supplemented by irradiation of the viscose to give a product of the desired viscosity, the latter serving to indicate the degree of depolymerization.  Irradiation may be carried out between room temperature and -78 DEG  C. on cellulosic raw materials, e.g. wood pulp in sheet or shredded form and cotton linters.  Wood pulp in continuous sheet form may be irradiated as it is unwound.  It is preferred to irradiate cellulose sheet of low moisture content. Examples describe the irradiation of cotton linters, wood pulp and viscose with electron beams and with X-rays from a gold target which has been bombarded by electrons.ALSO:A controlled depolymerization of cellulose is effected by subjecting cellulose to ionizing radiation of an intensity between 0.05 and 60 watt-second/gram of cellulose.

Abstract: 197,357. Rigby, T. Jan. 4, 1922. Flotation processes.-Solid fuels such as coal, lignite, peat, and the like are concentrated in such a way as to obtain the different grades in the forms best suited for their respective uses. The coal is ground, graded by a wet process such as frothflotation, and the different portions are dried separately. The greater portion of the coal is obtained in such a form that it contains only a little non-combustible ingredient and is suitable, without further grinding, for treatment in coking ovens for the production of metallurgical coke. The low grade residue obtained is further ground, before or after drying, for use in powdered fuel burners. Specifications 429/12, 175,004 and 182,157, [all in Class 34 (ii) , Drying systems &c.] are referred to.

Abstract: 454,788. Colour photography. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.-(I. G. Farbenindustrie Akt.- Ges.; Frankfort-on-Main, Germany) Jan. 5, 1935, No. 439. [Class 98 (ii)] A multilayer material comprises three superimposed colour-sensitive emulsion layers containing no colouring matter for the finished pictures or colour former therefor, arranged without intermediate filter layers in the order ; blue-sensitive, green-sensitive and red-sensitive with the blue sensitive layer adapted first to receive the incident light, each emulsion layer being fine-grained and rich in silver. The use of fine-grained emulsions rich in silver makes greater the ratio of the sensitivity in the region of special sensitization to the natural sensitivity of the emulsion in the blue region. The specific blue sensitivity of the sensitized emulsions may be damped by dyeing them with a yellow dyestuff. A high content of silver is obtained as described in Specification 426,866. When the material is used for the production of pictorial swollen reliefs for imbibition printing, the emulsion layers may be hardened to a high degree as described in Specification 447,488.

Abstract: 1,067,252. Valves. NORTH AMERICAN AVIATION Inc. Jan. 6, 1965 [April 1, 1964]. No. 633/65. Heading F2V. [Also in Division G3] A valve 201 is responsive to the pressures P s1 , P s2  of two sources to connect one source only to a load connected to a line 22 and to switch to the other source should the connected source fall below a proportion of the pressure of the other source. The valve also controls the connection of the outlet of the load in a line 23 to passages 15, 16 connected to the respective sources. With the valve in the position shown, source P s1  is connected to the load line 22 and the return 23 to passage 15. The pressure P s1  acts on areas 212, 213 of the valve 201 while the pressure P s2  acts on area 215. When the valve 201 moves to the right due to an excess pressure difference, the source P s2  is connected to the load line 22 through passage 28 and also acts on area 222 due to the connecting passages 221, 220 in the valve. The pressure P s1  now only acts on area 213. Movement of the valve also changes the connection of return line 23 to the passage 16 connected to the second source. Two change-over valves controlled by a pilot valve may be provided (see Division G3).
